@chapter Installation
@cindex Installation

This section describes the installation of pcl-cvs, the GNU Emacs CVS
front-end.  You should install not only the elisp files themselves, but
also the on-line documentation so that your users will know how to use
it.  You can create typeset documentation from the file
@file{pcl-cvs.texinfo} as well as an on-line info file.  The following
steps are also described in the file @file{INSTALL} in the source
directory.

@section Installation of the pcl-cvs program
@cindex Installation of elisp files

@enumerate
@item
Possibly edit the file @file{Makefile} to reflect the situation at your
site.  We say "possibly" because the version of pcl-cvs included with
CVS uses a configuration mechanism integrated with the overall
mechanisms used by the CVS build and install procedures.  Thus the file
@code{Makefile} will be generated automatically from the file
@code{Makefile.in}, and it should not be necessary to edit it further.

If you do have to edit the @file{Makefile}, the only things you have to
change is the definition of @code{lispdir} and @code{infodir}.  The
elisp files will be copied to @code{lispdir}, and the info file(s) to
@code{infodir}.

@item
Configure pcl-cvs.el

There are a couple of pathnames that you have to check to make sure that
they match your system.  They appear early in the file
@samp{pcl-cvs.el}.

@strong{NOTE:}  If your system is running emacs 18.57 or earlier you MUST
uncomment the line that says:
@example
(setq delete-exited-processes nil)
@end example

Setting @code{delete-exited-processes} to @code{nil} works around a bug
in emacs that causes it to dump core.  The bug was fixed in emacs
18.58.@refill

@item
Release 1.05 and later of pcl-cvs requires parts of the Elib library,
version 1.0 or later.  Elib is available via anonymous ftp from
prep.ai.mit.edu in @file{pub/gnu/elib-1.0.tar.gz}, and from a lot of
other sites that mirror prep.  Get Elib, and install it, before
proceeding.

@strong{NOTE:} The version of pcl-cvs included with CVS includes a copy
of Elib in the sub-directory @file{elib} under the
@file{contrib/pcl-cvs} directory.

@item
Type @samp{make install} in the source directory.  This will
byte-compile all @file{.el} files and copy the @file{*.elc} files into
the directory you specified in step 1.

If you want to install the @file{*.el} files too, you can type
@samp{make install-el} to do so.

If you only want to create the compiled elisp files, but don't want to
install them, you can type @samp{make} without parameters.

@item
Edit the file @file{default.el} in your emacs lisp directory (usually
@file{/usr/gnu/lib/emacs/site-lisp} or something similar) and enter the
contents of the file @file{pcl-cvs-startup.el} into it.  It contains a
couple of @code{auto-load}s that facilitates the use of pcl-cvs.

The current release of pcl-cvs is included in CVS-1.7.

The author's release of pcl-cvs can be fetched via anonymous ftp from
@code{ftp.lysator.liu.se}, (IP no. 130.236.254.1) in the directory
@code{pub/emacs}.  If you don't live in Scandinavia you should probably
check with archie to see if there is a site closer to you that archives
pcl-cvs.

New releases will be announced to appropriate newsgroups.  If you send
your email address to me I will add you to my list of people to mail
when I make a new release.


@node Getting started, Buffer contents, About pcl-cvs, Top
@comment  node-name,  next,  previous,  up

@chapter Getting started
@cindex Introduction
@cindex Example run

This document assumes that you know what CVS is, and that you at least
knows the fundamental concepts of CVS.  If that is not the case you
should read the man page for CVS.

Pcl-cvs is only useful once you have checked out a module.  So before
you invoke it you must have a copy of a module somewhere in the file
system.

You invoke pcl-cvs by typing @kbd{M-x cvs-update RET}.  If your emacs
responds with @samp{[No match]} your system administrator has not
installed pcl-cvs properly.  Try @kbd{M-x load-library RET pcl-cvs RET}.
If that also fails - talk to your root.  If it succeeds you might put
this line in your @file{.emacs} file so that you don't have to type the
@samp{load-library} command every time you wish to use pcl-cvs:

@example
(autoload 'cvs-update "pcl-cvs" nil t)
@end example

The function @code{cvs-update} will ask for a directory.  The command
@samp{cvs update} will be run in that directory.  (It should contain
files that have been checked out from a CVS archive.)  The output from
@code{cvs} will be parsed and presented in a table in a buffer called
@samp{*cvs*}.  It might look something like this:

@example
PCL-CVS release 1.05-CVS-1.7.
@comment -release-

In directory /users/ceder/FOO/test:
  Updated     bar
  Updated     file.txt
  Modified ci namechange
  Updated     newer

In directory /users/ceder/FOO/test/sub:
  Modified ci ChangeLog
---------- End -----
@end example

In this example the two files (@file{bar}, @file{file.txt}, and
@file{newer}) that are marked with @samp{Updated} have been copied from
the CVS repository to @file{/users/ceder/FOO/test/} since someone else
have checked in newer versions of them.  Two files (@file{namechange}
and @file{sub/ChangeLog}) have been modified locally, and needs to be
checked in.

You can move the cursor up and down in the buffer with @kbd{C-n} and
@kbd{C-p} or @kbd{n} and @kbd{p}.  If you press @kbd{c} on one of the
@samp{Modified} files that file will be checked in to the CVS
repository.  @xref{Committing changes}.  You can press @kbd{x} to get rid
of the "uninteresting" files that have only been @samp{Updated} (and
don't require any further action from you).@refill

You can also easily get a @samp{diff} between your modified file and the
base version that you started from, and you can get the output from
@samp{cvs log} and @samp{cvs status} on the listed files simply by
pressing a key (@pxref{Getting info about files}).

The @samp{file status} field can have the following values:

@table @samp

@item Updated
The file was brought up to date with respect to the repository.  This is
done for any file that exists in the repository but not in your source,
and for files that you haven't changed but are not the most recent
versions available in the repository.@refill

@item Patched
The file was brought up to date with respect to a remote repository by
way of fetching and applying a patch to the file in your source.  This
is done for any file that exists in a remote repository and in your
source; of which you haven't changed locally but is not the most recent
version available in the remote repository.@refill

@item Modified
The file is modified in  your  working  directory, and there was no
modification to the same file in the repository.@refill

@item Merged
The file is modified in your working directory, and there were
modifications in the repository as well as in your copy, but they were
merged successfully, without conflict, in your working directory.@refill

@item Conflict
A conflict was detected while trying to merge your changes to @var{file}
with changes from the source repository.  @var{file} (the copy in your
working directory) is now the output of the @samp{rcsmerge} command on
the two versions; an unmodified copy of your file is also in your
working directory, with the name @file{.#@var{file}.@var{version}},
where @var{version} is the RCS revision that your modified file started
from.  @xref{Viewing differences}, for more details.@refill

@item Added
The file has been added by you, but it still needs to be checked in to
the repository.@refill

@item Removed
The file has been removed by you, but it needs to be checked in to the
repository.  You can resurrect it by typing @kbd{a} (@pxref{Adding and
removing files}).@refill

@item Unknown
A file that was detected in your directory, but that neither appears in
the repository, nor is present on the list of files that CVS should
ignore.@refill

@end table

There are also a few special cases, that rarely occur, which have longer
strings in the fields:

@table @samp
@item Removed from repository
The file has been removed from your directory since someone has removed
it from the repository.  (It is still present in the Attic directory, so
no permanent loss has occurred).  This, unlike the other entries in this
table, is not an error condition.@refill

@item Removed from repository, changed by you
You have modified a file that someone have removed from the repository.
You can correct this situation by removing the file manually (see
@pxref{Adding and removing files}).@refill

@item Removed by you, changed in repository
You have removed a file, and before you committed the removal someone
committed a change to that file.  You could use @kbd{a} to resurrect the
file (see @pxref{Adding and removing files}).@refill

@item Move away @var{file} - it is in the way
For some reason CVS does not like the file @var{file}.  Rename or remove
it.@refill

@item This repository is missing!  Remove this dir manually.
It is impossible to remove a directory in the CVS repository in a clean
way.  Someone have tried to remove one, and CVS gets confused.  Remove
your copy of the directory.@refill
@end table


@node Selected files,  , File status, Buffer contents

@section Selected files
@cindex Selected files

Many of the commands works on the current set of @dfn{selected} files.

@itemize @bullet
@item
If there are any files that are marked they constitute the set of
selected files.@refill

Otherwise, if the cursor points to a file, that file is the selected

This scheme might seem a little complicated, but once one get used to

Run a @samp{cvs update} command.  You will be asked for the directory in

pcl-cvs, and the result printed in the @samp{*cvs*} buffer (see
@pxref{Buffer contents} for a description of the contents).@refill

By default, @samp{cvs-update} will descend recursively into
subdirectories.  You can avoid that behavior by giving a prefix
argument to it (e.g., by typing @kbd{C-u M-x cvs-update RET}).@refill

All other commands in pcl-cvs requires that you have a @samp{*cvs*}

CVS uses lock files in the repository to ensure the integrity of the
data files in the repository.  They might be left behind i.e. if a
workstation crashes in the middle of a CVS operation.  CVS outputs a
message when it is waiting for a lock file to go away.  Pcl-cvs will
show the same message in the *cvs* buffer, together with instructions
for deleting the lock files.  You should normally not have to delete
them manually --- just wait a little while and the problem should fix
itself.  But if the lock files doesn't disappear you can delete them
with @kbd{M-x cvs-delete-lock RET}.@refill

@item g
This will run @samp{cvs update} again.  It will always use the same
buffer that was used with the previous @samp{cvs update}.  Give a prefix
argument to avoid descending into subdirectories.  This runs the command
@samp{cvs-mode-update-no-prompt}.@refill

@item G
This will run @samp{cvs update} and prompt for a new directory to
update.  This runs the command @samp{cvs-update}.@refill

the fact that the buffer is a pcl-cvs buffer:

@item c
All files that have a "need to be checked in"-marker (@pxref{Buffer
contents}) can be checked in with the @kbd{c} command.  It checks in all
selected files (@pxref{Selected files}) (except those who lack the
"ci"-marker - they are ignored).  Pressing @kbd{c} causes
@code{cvs-mode-commit} to be run.@refill

When you press @kbd{c} you will get a buffer called
@samp{*cvs-commit-message*}.  Enter the log message for the file(s) in
it.  When you are ready you should press @kbd{C-c C-c} to actually
commit the files (using @code{cvs-edit-done}).

Normally the @samp{*cvs-commit-message*} buffer will retain the log
message from the previous commit, but if the variable
@code{cvs-erase-input-buffer} is set to a non-@code{nil} value the
buffer will be erased.  Point and mark will always be located around the
entire buffer so that you can easily erase it with @kbd{C-w}
(@samp{kill-region}).@refill

If you are editing the files in your emacs an automatic
@samp{revert-buffer} will be performed.  (If the file contains
@samp{$@asis{Id}$} keywords @samp{cvs commit} will write a new file with
the new values substituted.  The auto-revert makes sure that you get
them into your buffer).  The revert will not occur if you have modified
your buffer, or if @samp{cvs-auto-revert-after-commit} is set to
@samp{nil}.@refill

@item C
This is just like @samp{cvs-mode-commit}, except that it tries to
provide appropriate default log messages by looking at the
@samp{ChangeLog}s in the current directory.  The idea is to write your
ChangeLog entries first, and then use this command to commit your
changes.  Pressing @kbd{C} causes @code{cvs-mode-changelog-commit} to be
run.@refill

To select default log text, pcl-cvs:
@itemize @minus
@item
finds the ChangeLogs for the files to be checked in;
@item
verifies that the top entry in the ChangeLog is on the current date and
by the current user; if not, no default text is provided;
@item
search the ChangeLog entry for paragraphs containing the names of the
files we're checking in; and finally
@item
uses those paragraphs as the default log text in the
@samp{*cvs-commit-message*} buffer.
@end itemize

You can then commit the @samp{ChangeLog} file once per day without any
log message.@refill

repository.@refill

This command can also be used on @samp{Removed} files (before you commit
them) to resurrect them.

Selected files that are neither @samp{Unknown} nor @samp{Removed} will
be ignored by this command.

The command that is run is @code{cvs-mode-add}.

@item r
This command removes the selected files (after prompting for
confirmation).  The files are @samp{rm}ed from your directory and
(unless the status was @samp{Unknown}; @pxref{File status}) they will
also be @samp{cvs remove}d.  If the files were @samp{Unknown} they will
disappear from the buffer.  Otherwise their status will change to
@samp{Removed}, and you must use @kbd{c} (@samp{cvs-mode-commit},
@pxref{Committing changes}) to commit the removal.@refill

The command that is run is @code{cvs-mode-remove-file}.

@item cvs-auto-revert-after-commit
If this variable is set to any non-@samp{nil} value any buffers you have
that visit a file that is committed will be automatically reverted.
This variable is default @samp{t}.  @xref{Committing changes}.@refill

@item cvs-update-prog-output-skip-regexp
The @samp{-u} flag in the @file{modules} file can be used to run a command
whenever a @samp{cvs update} is performed (see cvs(5)).  This regexp
is used to search for the last line in that output.  It is normally set
to @samp{"$"}.  That setting is only correct if the command outputs
nothing.  Note that pcl-cvs will get very confused if the command
outputs @emph{anything} to @samp{stderr}.

@item cvs-cvsroot
This variable can be set to override @samp{CVSROOT}.  It should be a
string.  If it is set then everytime a cvs command is run it will be
called as @samp{cvs -d @var{cvs-cvsroot}@dots{}}  This can be useful if
your site has several repositories.

@item TMPDIR
Pcl-cvs uses this @emph{environment variable} to decide where to put the
temporary files it needs.  It defaults to @file{/tmp} if it is not set.

@item cvs-commit-buffer-require-final-newline
When you enter a log message in the @samp{*cvs-commit-message*} buffer
pcl-cvs will normally automatically insert a trailing newline, unless
there already is one.  This behavior can be controlled via
@samp{cvs-commit-buffer-require-final-newline}.  If it is @samp{t} (the
default behavior), a newline will always be appended.  If it is
@samp{nil}, newlines will never be appended.  Any other value causes
pcl-cvs to ask the user whenever there is no trailing newline in the
commit message buffer.

@item cvs-sort-ignore-file
If this variable is set to any non-@samp{nil} value the
@file{.cvsignore} will always be sorted whenever you use
@samp{cvs-mode-ignore} to add a file to it.  This option is on by
default.

@chapter Future enhancements
@cindex Enhancements

Pcl-cvs is still under development and needs a number of enhancements to
be called complete.  Below is my current wish-list for future releases
of pcl-cvs.  Please, let me know which of these features you want most.
They are listed below in approximately the order that I currently think
I will implement them in.

@itemize @bullet
@item
Rewritten parser code.  There are many situations where pcl-cvs will
fail to recognize the output from CVS.  The situation could be greatly
increased.

@item
@samp{cvs-status}.  This will run @samp{cvs status} in a directory and
produce a buffer that looks pretty much like the current *cvs* buffer.
That buffer will include information for all version-controlled files.
(There will be a simple keystroke to remove all "uninteresting" files,
that is, files that are "Up-to-date").  In this new buffer you will be
able to update a file, commit a file, et c.  The big win with this is
that you will be able to watch the differences between your current
working file and the head revision in the repository before you update
the file, and you can then choose to update it or let it wait for a
while longer.

@item
Log mode.  When this mode is finished you will be able to move around
(using @kbd{n} and @kbd{p}) between the revisions of a file, mark two of
them, and run a diff between them.  You will be able to hide branches
(similar to the way you can hide sub-paragraphs in outline-mode) and do
merges between revisions.  Other ideas about this are welcome.

@item
The current model for marks in the *cvs* buffer seems to be confusing.
I am considering to use the VM model instead, where marks are normally
inactive.  To activate the mark, you issue a command like
@samp{cvs-mode-next-command-uses-marks}.  I might implement a flag so
that you can use either version.  Feedback on this before I start coding
it is very welcome.

@item
It should be possible to run commands such as @samp{cvs log}, @samp{cvs
status} and @samp{cvs commit} directly from a buffer containing a file,
instead of having to @samp{cvs-update}.  If the directory contains many
files the @samp{cvs-update} can take quite some time, especially on a
slow machine.  I planed to put these kind of commands on the prefix
@kbd{C-c C-v}, but that turned out to be used by for instance c++-mode.
If you have any suggestions for a better prefix key, please let me know.

@item
Increased robustness.  For instance, you can not currently press
@kbd{C-g} when you are entering the description of a file that you are
adding without confusing pcl-cvs.

@item
Support for multiple active *cvs* buffers.

@item
Dired support.  I have an experimental @file{dired-cvs.el} that works
together with CVS 1.2.  Unfortunately I wrote it on top of a
non-standard @file{dired.el}, so it must be rewritten.@refill

@item
An ability to send user-supplied options to all the cvs commands.

@item
Pcl-cvs is not at all clever about what it should do when @samp{cvs
update} runs a program (due to the @samp{-u} option in the
@file{modules} file --- see @samp{cvs(5)}).  The current release uses a
regexp to search for the end.  At the very least that regexp should be
configured for different modules.  Tell me if you have any idea about
what is the right thing to do.  In a perfect world the program should
also be allowed to print to @samp{stderr} without causing pcl-cvs to
crash.

If you miss something in this wish-list, let me know!  I don't promise
that I will write it, but I will at least try to coordinate the efforts
of making a good Emacs front end to CVS.  See @xref{Bugs} for
information about how to reach me.@refill

So far, I have written most of pcl-cvs in my all-to-rare spare time.  If
you want pcl-cvs to be developed faster you can write a contract with
Signum Support to do the extension.  You can reach Signum Support by
email to @samp{info@@signum.se} or via mail to Signum Support AB, Box
2044, S-580 02 Linkoping, Sweden.  Phone:  +46 (0) 13 - 21 46 00.  Fax:
+46 (0) 13 - 21 47 00.

If you have ideas for improvements, or if you have written some
extensions to this package, I would like to hear from you.  I hope that
you find this package useful!

Below is a partial list of currently known problems with pcl-cvs version
1.05.

@table @asis
@item Commit causes Emacs to hang
Emacs waits for the @samp{cvs commit} command to finish before you can
do anything.  If you start a background job from the loginfo file you
must take care that it closes @samp{stdout} and @samp{stderr} if you do
not want to wait for it.  (You do that with @samp{background-command &>-
2&>- &} if you are starting @samp{background-command} from a
@samp{/bin/sh} shell script).

Your emacs will also hang if there was a lock file in the repository.
In this case you can type @kbd{C-g} to get control over your emacs
again.

@item Name clash in Emacs 19
This is really a bug in Elib or the Emacs 19 distribution.  Both Elib and
Emacs 19.6 through at least 19.10 contains a file named
@file{cookie.el}.  One of the files will have to be renamed, and we are
currently negotiating about which of the files to rename.

@item Commands while cvs-update is running
It is possible to type commands in the *cvs* buffer while the update is
running, but error messages is all that you will get.  The error
messages should be better.

@item Unexpected output from CVS
Unexpected output from CVS confuses pcl-cvs.  It will currently create a
bug report that you can mail to me.  It should do something more
civilized.
